井身结构设计是钻井工程设计的基础。根据对福山油田地质岩性特征、地层压力系统及复杂地层已完钻井实钻情况的统计归纳，研究了近两年所钻72口井现有井身结构设计应用情况、钻井技术指标及井下复杂情况。研究表明，虽然现有井身结构基本能够满足勘探开发钻井的需求，但仍有优化的空间使其井身结构设计更具有灵活性、动态性，以进一步提高机械钻速、节约钻井投资成本。

This article discusses Fushan Oilfield from its geologic lithology features ,formation pressure system to practical drilling in its complex formation and studies the application of current borehole configuration design of drilled 72 wells of the past two years .The research shows that although the current borehole configuration can largely meet exploration and production drilling ,its design can be improved to raise the rate of penetration and re‐duce the cost of drilling investment .
